LANTERN.

SPECIFICATION forming part of Letters Parent No. 371,898, atea ocrcber 18, 1887.

Application tiled June 15, 1886. Serial No. 205,205. (No model.)

To all whom it may concern:

Be it known that I, Jol-IN W. MURPHY, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Lanterns; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form 1o a part of this specification. l

This invention relates to that class of lanterns or lamps in which the globe or chimney and the base-plate supporting the globe are raised a short distance for the purpose of giving access to the wick inlighting the lamp.

rlhe invention has more particular reference to devices for directing the globe in its vertical movements and holding the globe in its raised position. Vhen applied to lanterns y from which the globe is removable laterally,

it also has reference to means for allowing a rocking movement of the perforated plate on which the globe rests in order to facilitate such lateral removal of the globe.

In the accompanying drawings, Figure l represents my improvement applied to a socalled tubular lantern,7 from which the globe is removable laterally. Figs. 2 and 3 are details of the construction shown in Fig.

3o l. Fig. 4 shows the invention applied to an ordinary railroad-lantern.

A represents the base or bottom of the frame, B the top, and C C uprights which connect the top and bottom of the parts of a lantern- 3 5 frame o'f this style.

D is the globe. E is the base-plate on which the globe rests, and F of Fig. l is a springactuated presser which holds the globe down. Said plate E has a central opening to admit 4o the burner-dome G, and is commonly provided with perforations to admit air te the globe from below.

In Fig. l the nprights C C are tubular; but in Fig. 2 they are solid wires.

4,5' In applying my invention to a lantern the base-plate E is provided with perforated opposite ears e, which may be in the form of wire loops soldered to the plate E, as shown.

H H are two vertical stationary wires secured in any suitable manner to the frame-- as, for example, to the uprights C C-in position to pass through the ears e e, and they thus serve as guides for the plate E when the latter is lifted or lowered. All that is necessary, therefore, in lighting the lantern is to 5 5 push upwardly against the base-plate E until the wick is accessible, and after lighting to allow it to drop, in which operation the guidewires direct the plate to its proper position.

In prior constructions the base or bottom 6o plate, 'corresponding to the plate E here shown, has been made upwardly movable, and has been guided in such upward move- 'ment by guiding rods or wires, which, however, had no other purpose or adaptation than simply to direct the plate in such vertical movement. In my improvement these guiding-wires are also made to retain the plate and the globe thereon, if necessary, in an elevated position in order that the operation of light- 7o ing the lamp may be more easily performed; and to this end I prefer to make the wires upwardly divergent in order that the ears e may bind thereon somewhat, and thus, by friction of the ears on the wires, hold or assist in holdv ing the cap at a desired elevation. Such deilection of one of the wires is shown at 7i. I also prefer to provide a shoulder, as h-,in one of said wires, which will positively hold the plate E when the adjacent loop or ear e is SO pushed to that point. rIhe wire, of course, `is of proper size and material to spring in this operation sufficient to allow the desired movement of the base-plate with appropriate ease.

In connection with a lantern from which the globe is laterally removable, an advantagev of stationary vertical wires H H, located at diametrically-opposite sides of the lantern and engaged with the opposite ears e on the plate E, the latter being also unconnected with the go top plate which supports the upper end of the globe, is that the said plate E is permitted to tilt, as indicated in Fig. 8, to facilitate the removal and insertion of the globe. W'hen this purpose is had in view, and the form oi' the 9 5 lantern is that shown in Fig. 1, it will be desirable to give the wires H and H', or one of them, the lateral bend shown at 7L', by which they support the base-plate E with certainty at a proper distance above the base of the cone Ioo G to allow a more free rocking movement, and in the case of either form of lantern illustrated such shoulder or shoulders h will positively sustain the globe and base-plate E when it is only desired to light the wick.

Dotted lines in Fig. l show the guide-wires H II extended directly down to the horizontal part of the tubes C C instead of being Y bent outward into connection with the vertinot free to tilt and to thereby facilitate the removal of' the globe. In the construction here described,wherein stationary guide-wires are used in connection with a base-plate engaged therewith, and the base-plate is connected with the upper part of the lantern, the base-plate is raised by pressing upward against it with the thumb of one hand while pressing down with the fingers ofthe same hand against the adjacent part of the lanternbody, thus leaving one hand free to apply the match to the wick, and in the case of the lantern having the laterally-removable globe, when it is desired to so remove the globe, the base-plate is free to tilt and thus facilitate the withdrawal or the insertion of the globe.

I claim as my invention- 1. The combination, with a lantern-frame,

of a vertically movable globe supporting plate, and a stationary laterallyspringing guide or guides engaged with and directing the vertical movement of said plate and also exerting the force of their springing action upon the globe supporting plate, substantially as described.

2. The combination, with a lantern-frame, of a vertically movable globe supporting plate, E, provided with opposite perforated ears, and fixed upright spring-guides engaged with said ears and diverging upwardly in that part of their length embraced in the range of vertical movement of the plate E, substantially as described.

3. The combination, with a lantern-frame, of -a movable globe-supporting plate, E, provided with opposite perforated ears, and two guide-wires engaged with said ears, one of said wires being provided with an upwardly and outwardly inclined part, h, and shoulder h', substantially as described.

4. The combination, with alantern-frame, of a vertically movable globe supporting plate, and stationary Vertical guide-wires for said plate engaged therewith and located on op'posite sides of the plate, said plate being otherwise free and having its points of engagement with the guides in substantially the same plane as the body of the plate, whereby the latter may be rocked on its bearing-points upon said guides, substantially as described.

In testimony that I claim the foregoing as my invention I afx my signature in presence of two witnesses.
